An integrated model of perennial and annual crop production for Sub-Saharan countries

Robert Weaver

No 175, Policy Research Working Paper Series from The World Bank

Abstract: Crop production in sub-Saharan Africa is dominated by smallholders who allocate household labor across annual and perennial crops and, in some cases, to wage labor markets. This paper develops a microeconomic model of household choice which is consistent with observed characteristics of sub-Saharan agricultural systems in terms of: integrated production of annual and perennial crops; price uncertainty in markets that may be affected by government intervention; the potential for off-farm employment; household consumption of crops produced on the farm; and household consumption of non-food goods, school fees and so on. The paper considers variations in the model to establish their implications. These variations include differential buying and selling prices, fixed subsistence consumption constraints, participation in wage market labor, smuggling in response to government price control, and parallel markets with penalties for smuggling.
